Greetings all,

We would like to invite you to submit abstracts for oral and poster
presentations for **Theme 10: Organismal physiology, adaptation and
acclimation– What role does phenotypic plasticity play in acclimatization
or adaptation to environmental change?**

Abstract Deadline: 1 September 2019

Session Description:
Plasticity is the ability of an individual to produce a range of phenotypes
in response to environmental variation. Understanding the drivers and
consequences of phenotypic variation is critical for predicting organismal
responses to environmental change. Many marine organisms encounter
environments favoring different phenotypic optima, however the relationship
between the direction and magnitude of plasticity and fitness (survival
and/or reproduction) remains unknown. While prior experience can
significantly alter subsequent responses to stress, the importance of
time-lags between cue and response, as well as the capacity for
reversibility remain unexplored. The mechanisms giving rise to plasticity
are also unresolved, but may include genetic and non-genetic mechanisms
that can function at different levels of the holobiont (an organism and its
associated microbiota). Given that environments are rapidly changing,
phenotypic plasticity that may have previously been essential to
efficiently respond to certain environments might become adaptive. Finally,
for certain taxa, such as corals, understanding how plasticity shapes
responses to novel reef environments will be critical to the success of
applied restoration activities. This session is focused on understanding
the role(s) that plasticity might play in acclimatization or adaptation of
reef organisms to environmental change.

Specifically, the session will focus on the following questions:
-Are plastic changes in phenotype adaptive in novel environments?
-Are changes in plasticity heritable?
-Does the magnitude of plasticity differ among populations or species?
-How does environmental history shape plasticity?
-What molecular mechanisms underpin the capacity for plasticity?
-Is the capacity for plasticity limited ontogenetically?
-What is the role of symbiosis and/or the microbiome in plasticity?
